Benchmarking Coaxial and Angular Optical Emission Spectroscopy With Recommendations for Reliable Compositional In Situ Monitoring During Laser Powder Bed Fusion

Advanced Materials Technologies, EarlyView.
ABSTRACT Real‐time insight into local chemistry is critical for reliable part quality in additive manufacturing, especially laser powder bed fusion (PBF‑LB/M), where rapid thermal cycles and localized evaporation can undermine part performance. Optical emission spectroscopy (OES) offers non‑intrusive, in situ plume monitoring, but detection geometry ...

Herd Behavior and Mutual Fund Performance

Management Science, 2017
I develop fund-level measures of the similarity in trading of mutual fund managers, resulting in the identification of leaders, contemporaneously herding managers, and followers. I find evidence of a persistent group of funds whose trades lead the aggregate trades of the mutual fund industry; these leader funds exhibit strong subsequent performance ...

The Persistence of Mutual Fund Performance

The Journal of Finance, 1992
ABSTRACTThis paper analyzes how mutual fund performance relates to past performance. These tests are based on a multiple portfolio benchmark that was formed on the basis of securities characteristics. We find evidence that differences in performance between funds persist over time and that this persistence is consistent with the ability of fund ...
